Wabbitemu

If you own or are familiar with graphing calculators, you probably wanted to find a way to use them from your computer or debug them.
Fortunately, Wabbitemu is one of the applications that can help you achieve satisfactory results in the situation mentioned above by providing you with all the necessary functions.

Emulate and debug graphing calculators

This application can help you emulate or debug various graphing calculators directly on your computer. The supported models include the TI-73, TI-81, TI-82, TI-83, TI-83+(SE), TI-84+(SE), TI-84+CSE, TI-85, and TI-86 calculators.
It is worth mentioning that this program can no longer download OS updates. New users are asked to locate a ROM file, whether they use an actual device and dump the software using a link cable or search for it on the Internet.

Easy to setup

After you download the application, there is no need to install it, since it is portable and simply launching its executable grants you total access to its functions. More so, you can run it from removable storage media.
It doesn't create any additional files or folders on your comnputer without your explicit permission and it doesn't tamper with any of your Windows registry entries. Before you can actually use it you need to load a ROM file by loading it from your computer, copying it from your physical calculator or creating a ROM based on an OS file.

Debugger included

After you load the ROM, you can view the device emulated on your computer and interact with it as you would with the physical device. It is possible to use the "View" menu's options to toggle the visibility of certain components or detach the LCD screen.
It also includes a debugger that can be accessed by selecting the "Open Debugger" option from the "Debug" menu or by pressing the F11 key on your keyboard.

Handy graphing calculator emulator and debugger

All things considered, Wabbitemu is a reliable application that can help you emulate and debug various graphing calculator models. It is portable and comes with a simple, intuitive interface, but, unfortunately, cannot download OS files anymore.
